Get Vertex Example (VBA)

This example shows how to get the x,y,z location of each vertex on the selected face:

• Query a face for edge information

• Traverse the topology of a part from the face down to the vertex

• Determine the selected object count

• Get objects selected by the user

• Determine object types
